दिए गए एसक्यूएल क्वेरी

Question

के लिए मानदंड क्वेरी कैसे बनाएं I इस समकक्ष एसक्यूएल क्वेरी के लिए आईसीआरटीरिया क्वेरी बना रहा हूं।

SELECT fCustomerID, 
     ISNULL(
       (SELECT SUM(payinv.fAmount) AS Expr1 
       FROM dbo.tARPayment AS pay 
       INNER JOIN dbo.tARPaymentInvoice AS payinv ON pay.fPaymentID = payinv.fPaymentID 
       INNER JOIN dbo.tARInvoice AS inv ON payinv.fInvoiceID = inv.fARInvoiceID 
       WHERE (pay.fIsPosted = CASE pay.fPaymentType WHEN 'CM' THEN 0 WHEN 'EPD' THEN 0 ELSE 1 END) 
        AND (inv.fCustomerID <> dbo.tARCustomer.fCustomerID) 
        AND (pay.fCustomerID = dbo.tARCustomer.fCustomerID)), 0) 
FROM dbo.tARCustomer 
GROUP BY fCustomerID 

लेकिन मुझे वैसे भी नहीं मिल रहा है कि मैं बराबर निबर्नेट आईसीआरटीरिया क्वेरी कैसे उत्पन्न कर सकता हूं।

Answer 1

बल्कि LINQ या HQL करने के लिए ऊपर जिज्ञासा को परिवर्तित करने के बजाय, मैं एक दृश्य में क्वेरी करने होंगे और फिर उस दृश्य क्वेरी करने के लिए NHibernate का उपयोग कर की सिफारिश करेंगे।

एसक्यूएल

CREATE VIEW vCustomerAmount AS 
SELECT fCustomerID, 
     ISNULL(
       (SELECT SUM(payinv.fAmount) AS Expr1 
       FROM dbo.tARPayment AS pay 
       INNER JOIN dbo.tARPaymentInvoice AS payinv ON pay.fPaymentID = payinv.fPaymentID 
       INNER JOIN dbo.tARInvoice AS inv ON payinv.fInvoiceID = inv.fARInvoiceID 
       WHERE (pay.fIsPosted = CASE pay.fPaymentType WHEN 'CM' THEN 0 WHEN 'EPD' THEN 0 ELSE 1 END)

        AND (pay.fCustomerID = dbo.tARCustomer.fCustomerID)), 0) [Amount]

GROUP BY fCustomerID 

सी # डीटीओ

public class CustomerAmount 
{ 
    public int fCustomerID { get; set; } 
    public decimal Amount { get; set; } 
} 

क्वेरी

List<CustomerAmount> customerAmounts = session.Query<CustomerAmount>().ToList(); 

Answer 2

नहीं

यकीन nHibernate के बारे में है, लेकिन करना क्या यह पुनः लिखा गया प्रश्न एक ही उत्तर प्राप्त करने में मदद करता है और ऐसा कुछ है जिसे आप आसानी से चला सकते हैं?

SELECT T.fCustomerID, 
     coalesce(SUM(payinv.fAmount), 0) as SumAmt 
    FROM 
     dbo.tARCustomer T 
     JOIN dbo.tARPayment AS pay 
      ON T.fCustomerID = pay.fCustomerID 
      AND pay.fIsPosted = CASE pay.fPaymentType 
           WHEN 'CM' THEN 0 
           WHEN 'EPD' THEN 0 
           ELSE 1 END 
      JOIN dbo.tARPaymentInvoice AS payinv 
       ON pay.fPaymentID = payinv.fPaymentID 
       INNER JOIN dbo.tARInvoice AS inv 
        ON payinv.fInvoiceID = inv.fARInvoiceID 
       AND inv.fCustomerID <> T.fCustomerID 
    GROUP BY 
     T.fCustomerID
